On the Symfony blog there's a recent post about a new effort being started to help improve REST in Symfony-based applications. William Durand talks about some of the current tools and some of the missing features/difficulties each has. This effort wants to help change that.

Building APIs with Symfony is not new. We've done that since the early beginning of Symfony: Askeet, Jobeet, it's been a long time! Nowadays, more and more web applications are made of an API and a client side application. Sharing data across applications using APIs also became an essential feature. [...] For most of us, it is not as clear as it should be, and we can certainly do better than what we have right now! Hence the creation of a working group to gather both people and knowledge for REST in Symfony: https://groups.google.com/forum/#!forum/resting-with-symfony.

The target of the group is just about anyone associated with the development of APIs: developers who build them, developers to contribute to Symfony's REST functionality, people with questions about REST and, really, anyone else interested. It's a part of their wider developer experience initiative they've recently ramped up.
